Yahoo's Market Movers

So I'm a newb, and you'll probably think I'm more of a newb for even considering this, but are there any strategies for taking advantage of stocks that get hammered and then bounce back the next day?

As for Price % Gainers... the last couple days I've been checking out which stocks have gained some momentum when the market has been open for an hour, and I've had about a 75% consistency at picking which will keep growing until about mid-day and lock in at least a 2% gain.
